How to restore scratchy turntable dustcovers with a polishing machine 

i did just what you did but i used a plastic polish and it worked great ,i restored a 1978 technics sl-d3 turntable dust cover. thanks for the tip.

Very good work. I just did this with my Technics SL-D202 dustcover. I first wet sanded with 2000 grit, then 3000 grit, then Meguiar's Ultimate Compound and Meguiar's Ultimate Polish on a Harbor Freight dual action long throw polisher. Perfect clarity. A little bit of the polish on a microfiber towel took the tarnishing off of the metal power and cue switches too.

Click 0:45 and then 19:45 to see de difference clearly ! ;) Great work !

hey ! I've just been doing exactely the same the last two days !!! I bought a stageline ing 220 turntable with a scatched cover for 60 €. I tried sanding with 400, 2000, 5000 sand paper, with water, toothpaste, Mirror... but it didn't really work. The cover became smooth, but still somewhat opaque. Eventually I got the polisher from my cellar, and that did the job ! Now my turntable is like new. My advice would be to start sanding with 400 paper to get rid of all the major scratches and make the surface homogeneous, and then do the polishing. you can do the sanding with the polishing machine, by putting a sheet of sanding paper between the cover and the polisher disk. Make sure all is clean, and no particules get between the cover and the polisher or you'll get little circles on your cover from the the elliptical movement of the polisher. Use a towel to lay down your cover rather than newspaper, it'll absorb the vibration.

Ah, great advice. Just bought a Pioneer PL-71 turntable with a really scratched up cover, and always wondered if a buffing wheel would work, until now.

Great tip about the cracking risk due to the heat - you probably saved a few covers. Nice to see the cream cleaning liquid works. I'd try a regular toothpaste. One caution with toothpastes or cleaning creams, some may contain some sort of grit so need check before using them.

I always wet-sand first, starting with 800, then 1000, then 1200, through 6000, and finally 12,000. These sanding assortment packs are available at Hobby Lobby. You can tell when each grit is finished by the feel of the paper as it glides across the surface. My final finishing is done with the buffer to an absolute crystal clear finish.

Good video and great job! When I’ve done work like this, I start off by wet sanding (fresh water with a few drops of liquid dish soap) with 2000 grit sandpaper. Wash it off and starting with clean water and repeat with 4000, 6000, and 8000 grit. Clean it off and then hand polish with Novus number 2 polish. It turns out clear as glass.

yeah i did this on an old 80's JVC goodwill find. it had lots of scratches and gouges. Used a buffing wheel that i put on my handdrill. the secret is to do it in maybe 10 to 20 second intervals and then check the plastic for excessive heat. too much heat will cause the plastic to get too hot and will craze (melt). if that happens, you have to sand it with sand paper and then try and polish it out. easiest just to take it slow and easy the first time!

Looks good Andrew, I avoid using paper towel napkins as they add to the swirling scraches. Always try to use a micro fiber or cotton or chamos to clean off right residual polish to guard against swirling. But for a first time using the wheel really nice job.

I think it is better if you add water to it as you are doing it Andrew...keeps it from drying out. Looked much better anyway

Turned out good. Two thumbs up!

Je kunt ook heel fijn schuurpapier gebruiken met heel veel water. Ik heb daar ooit de lampen van mijn Honda en een stofkap van een platenspeler mee gepolijst... helemaal helder!

Looks way better than it did. I have a few original dust-covers that would benefit from that treatment. To me,an original dust-cover is better than a new,reproduction one.

Thanks! I cannot wait to try this on my lid from 1980

Car polish would have been even better for the last step. It contains finer particles and wax this makes a perfect finish.

Hi friend like your videos you use a lot of common sense .But I like your ACCENT IN ENGLISH very funny . You called the DUST COVER A DOOOST COVER LOL . Keep the videos coming ....

I enjoyed your video immensely, Andrew. Keep up the good work!

First in was a Sony table. At 3:36 it became a Sansui. Then came the "This cream - lemon cream". Do yourself a favor - go to a yard sale and buy an old folding wood snack table. Your gonna kill your back like this.

I would use 1000 grit wet/dry paper, then a light hand polishing. In case you don't have a budget for a power polisher.

Good job Andrew. It was a great improvement. 'Very enjoyable video.

You just saved me 100Eu, nice job! Subscribed

Great job, but paper towel is made of wood particles and those scratch plexi...better use some micro-fiber cloth to clean.

Je kan het combineren met water dan word het niet zo warm en kun je langer polijsten. Je kan het verschil goed zien. Goede tip voor de mensen die dit niet weten. Leuke film dre.

Yes this is what i wanted you to do my cover is scratched

Good job but if you have old pillow to put under the plastic will make your job a lot easier and maybe you can put it on top of a table to make it easy on your back.

I like the restoration ! Very interesting video.

This vibration is making your floor behave alike a speaker diafragm..sound below is very high Andrew...living in an appartment it is better to put something soft below to block vibrations to go to your floor because it is a ceiling from the appartment below you.

A grear "system" for polishing plastic is.... NOVUS, Part 3 (corse compound), Part 2 (fine compound) and Part 1 (polymer sealer/polish). Use a small, true ORBITAL polisher, not a large rotary style A small orbital will not have heating issues (or unexpectedly throw the cover across the room). Most turntable covers, no matter how dull, have very fine scratches and you can skip the Novus 3. The top's always the worst, maybe lightly polish on the sides. Avoid the inside if possible, that area is usually in very good shape. Just wash it well. Think you're finished work?, let the polymer dry overnight and hand polish with a soft 100% COTTON cloth. Cloths with polyester blend will re-scratch it, damage your hsrd work and look less than perfectly clear. PS..... if it's really, really bad, you can wet sand it with 3000 to 5000 grit pads first. Initially, it will look "really bad" but will then clean right up with the compound. Works for me, LOTS and LOTS or times.

Great job! Thanks for posting!

Ik zou inderdaad een Car polish gebruiken Andre, geen jif of wat je daar ook hebt. Verder 2 tips: leg er altijd een houtblok onder. Dus dat de kap op het houtblok rust met polishen en niet op de zijkanten van de kap zelf. Dan kan je harder duwen, zonder angst voor breken/splijten van de zijkanten. Ook kan je zo de scharnieren "vrijhangen". Over het algemeen: gebruik water. Dat koelt de kap, kan je langer polijsten. 2e: ook de diepere krassen krijg je wel degelijk er uit, maar dan moet je gaan schuren. En dat doe je net als bij een autokoplamp: je begint met wetsanden korrel 1000. Daarna ga je naar fijner korrel 3000 en schuurt tot heel de kap perfect egaal/dof is. Dan ga je polijsten met een echte polijstpasta zodat de kap weer helder wordt. Daarna beetje in de wax zetten en de stofkap is net zo mooi als een nieuwe. Je kunt speciale setjes hiervoor bestellen op sites die gespecialiseerd zijn in "car-detailing" en "carcleaning".

Exactly the Same way I do it. Good instincts.

Wow looks good I have to do this

Are the kits that are made for polishing polycarbonate made car headlights would work for this too ?

I wish they made dust covers out of glass!

I love you man but your buffer was not spinning lol

Pain in the .... Cleaning - fair at best. Buying a new one - waste of money. Dust covers are the most useless and take away the aesthetics more than add. Acrylic and plastics seem to be just simply not the right material - and it hasn't been for years and years now. I don't get it.

Where do you buy cream? Don't think we have it in USA

Good video!

It will be very very shinny I will tell you that.

Can you that by hand, Sir?

¿'Plataforma giratoria"?

As they say in The Netherlands: stone coal English (steenkool Engels) 😉

You need a polish applicator that actually rotates. Those just vibrate and are pretty useless. Drill attachment polish head is much better. 2000 grit water paper then Meguires PlastX. I get them as new in about 15 minutes.

Hallo, wat gebruik u als polish cream ?

God job. 1 up from me

Best way 1000 grit 1500 grit then 3000 then wax it .

Thanks! Subscribed :-)

Who’s Bud?

cuantos minutos más vas a estar puliendo pelado??? con un par de minutos ya está!!!!

Dieses Ding ist Schrott! Die Haube geht kaputt und die Handgelenke auch.

AJAX!

Abbo erbij!!

Tout simplement génial ce truc! Bravo! J'adore! Et pour les plus petites surfaces ou les surfaces plus difficiles d'accès, je suggère l'utilisation du Dremel avec son accessoire à polir, évidement.
